1. 1. Varnishing of Fiber-based Closures

   Master-uppsats, Lunds universitet/Förpackningslogistik

   Författare :Nisha Sunil David; [2023]
   Nyckelord :Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

   Sammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER

4. 3. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Mehrzad Ghassemi; [2022]
   Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

   Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

5. 4. Continuous leaching of phosphorus from sewage sludge ash

   Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Sofie Göransson; [2022]
   Nyckelord :Ash leaching; Continuous stirred tank reactor; CSTR; Phosphorus recovery; Sewage sludge ash;

   Sammanfattning : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. LÄS MER

7. 5. Study of yield variation in a pharmaceutical manufacturing process and optimization of purification subsection : By a design of experiments study of the production parameters and a laboratory study of the purification step

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Sandra Lord; [2022]
   Nyckelord :Yield variations; activated carbon; pharmaceutical industry; purification; design of experiments; optimization; Utbytesvariation; aktivt kol; läkemedelsindustrin; reningssteg; experimentell design; optimering;

   Sammanfattning : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. LÄS MER
